Setting Data Resiliency
The data map contents stored in the disk array controller NVRAM is copied to two disks on the array at
regular intervals to protect against map loss. The interval at which the disks are updated with recovery map
information is controlled using the data resiliency setting. Selecting a data resiliency setting involves
making a tradeoff between data protection and performance. The more frequently the recovery maps are
updated, the more impact it may have on performance.
